TBX Wireless Load Cell Bridge

Key Features

The TBX Wireless Load Cell Bridge eliminates the need for cables when setting up a load cell and weight indicator, because it replaces the wire connection between the load cell and indicator

  • Ultra-low energy consumption
  • Clamp connectors (vibration resistant)
  • Additional LED module indicating system status
  • Low battery status indicator (via RS 232 port and LED diode)
  • Energy saving mode (sleep mode in absence of a change in mass value)
  • Receiver powered directly from load cell connector (no external power supply)
  • Multiple systems can be operated in one location (128 channels can be selected)

Available options: TBX Pair (R&T), TBX-R, TBX-T
